PAPER-BOX MACHINE.

SPECIFICATION forming part of Letters Patent No. 369,900, dated September 13, 1887.

Application filed June 3, 1855. Serial No. 167,540. (No model.)

To all whom it may concern.-

Be it known that I, MERRIcK F. WILsoN, I a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Paper-Box Machines, which are fully set forth in the following specification, reference being had to the accompanying drawings, in which Figure l is an elevation of a machine embodying my invention; Fig. 2, a planview of the same; Fig. 3, an enlarged sectional view taken on the line as x of Fig. 2; Fig. 4, a sectional view taken on the line y y of Fig. 1; Fig. 5, a sectional view taken on the line 2 .2

of Fig. 1; Fig. 6, a detail view, partly in sec tion, of the end of one of the spindles, showing one of the clamping-disks and its centering device; Fig. 7, a similar view of the end of the other spindle, showing the other clampingdisk and the boxholder; Fig. 8, a detail view of the yoke which operates the boxholder; Fig. 9, a face view of one of the clamp ing-disks; Fig. 10, a detail plan view of the mechanism for communicating motion to the spindle; Fig. 11, a view illustrating the rollertool employed in finishing the box, and Fig. 12 a sectional view of the complete box which my machine is designed to produce.

Like letters refer to like parts in all the figures of the drawings.

My invention relates to paper-box machines and more particularly to that class of machines wherein an already-formed box-body is united to the box-bottom by means of a covering of paper previously coated with paste, its object being to provide means whereby the operation of joining the body and bottom and applying the paste-covered paper may be readily and accurately performed; and to these ends .my invention consists in certain novel features,which I will now proceed to describe, and will then specifically point out in the claims.

In the drawings I have shown a machine in which my invention is practically carried out in one form, in which' A represents a suitable table upon which the various parts of the machine are supported. 50 Upon this table are mounted two frames, the

one, B, being preferably stationary, while the other, C, is mounted to slide in ways upon the table, as shown, so as 'to regulate its distance from the fixed frame B, a bolt, 0, passing through a slot in the table and receiving a nut, c, by means of which the movable frame may be clamped after adjustment. In suitable bearings in the frame B is mounted a revoluble spindle, D, having removably attached to its inner end a disk, 01, provided with small projections (1, three of these projections being shown in the present instance, though more or less than this number may be employed.

E indicates a spindle mounted in the frame O,with its axis in line with the axis of the 6 spindle D, and capable not only of revolution, but also of longitudinalmovements intheline of its axis. This spindle is provided with a terminal disk, 6, at its inner end, corresponding to the disk (1 of the spindle D. The disks d and c are shown in the present instance as screwed upon the ends of their respective spindles, so that they may be readily removed when desired, but will rotate along with the spindles when in place.

Upon the spindleD is mounted a sleeve, F,

capable of longitudinal motion upon the spindle, but caused to rotate withit by means of a pin, d upon the spindle,which enters-a slot, f, in the sleeve, or by any other approved means. Upon the end of this sleeve, adjacent to the disk d, is securedadisk, F, of larger diameter than the disk d, and having a peripheral fiange,f, the whole forming a centering device, as hereinafter described.

Upon the spindle E is mounted a sleeve, G, capable of longitudinal motion upon the spindle, and having attached to its inner end the box-holder G, consisting of a cylindrical body attached to a disk, which latter projects some- 0 what beyond the body and forms a terminal flange, g. Both the centerer and box-holder are shown as screwed upon their respective sleeves, so that they may be readily removed, though they may be otherwise attached, if desired.

H indicates a lever, which is pivoted at its rear end to the frame 0 and extends forward under the spindle E, to which it is connected by means of a screw or pin, 71, attached to a seeoo sleeve, 6, mounted on the spindle between two collars, so as to permit the spindle to revolve freely within the sleeve, but at the same time participate in the longitudinal motion imparted to the sleeve by the lever.

I indicates a second lever, also pivoted at its rear end to the frame 0, and extending forward and connected by a pin, 1', passing through a slot in the lever, to a sleeve, I, mounted between collars on a rod, I ,which passes through the sleeve, and is itself mounted in the frame 0, so as to be capable of longitudinal motion. A spring, i, of rubber or metal, is arranged between the inner end of the sleeve 1 and the adjacent collar, for the purposes hereinafter described. On the inner end of the rod I is arranged a yoke, 1 constructed substantially as shown in Figs. 7 and 8 of the drawings, the said yoke being embraced between collars g on the sleeve G, so as to allow the said sleeve to rotate freely, but to cause it to partake of the longitudinal motion imparted to the rod I by means of the lever I. A stop, 1', is secured upon the end of the rod P, which projects beyond the frame 0, the said stop limiting the inward motion of the rod by its contact with the frame,and consisting,preferably, of a sleeve provided with a set-screw, by means of which it can be secured at various points on the rod after adjustment. I

The levers H and I extend outward over and rest upon the front bars, J, of the frame 0, and these bars are provided with conical enlargementsj, forming inclines terminating on the inner side in abrupt shoulders, so that the levers while in operation will ride over the said inclines and drop behind the shoulders, and thereby be locked to prevent any accidental return movement of the levers. An adjustable stop, j, similar in construction with the the stop t", is provided upon the lower bar, over which the lever H travels, to limit the movement of the said lever in an inward direction. A stop similar to the stop j may be employed upon the upper bar J to limit the movement of the lever I, the stop '5 being dispensed with in that case; or, instead of the stop j, a stop similar to the stop i may be arranged upon the end of the spindle E.

In order to render the fulcra of the levers H and I adjustable, for the purposes hereinafter described, these levers are pivoted to sleeves mounted loosely upon one of the rear crossbars of the frame 0, and secured after adjustment by set-screws in an obvious manner.

In order to impart a rotary motion to the spindle D, I'mount upon the said spindle a large friction-pulley, K, and a small frictionpulley, k. The large pulley K is arranged immediately below a pulley, K, of smaller diameter, mounted on a shaft, K", journaled in arms K projecting from a rock shaft, K, mounted in suitable bearings in the frame B. The shaft K 'is operated by means of a belt, L, passing over differential pulleys Z on the said shaft and upon the drive-shaft L.

M indicates an arm attached to the rock- 'unites them and completes the box.

shaft K, and having pivoted to it the upper end of a connecting-rod, m, the lower end of which is attached to a foot-lever, M. A spiral spring, m, is arranged between the top of the table A and a stop, m on the rod m, and exerts an upward pressure on the said rod, which keeps the friction-pulley K somewhat above the pulley K in'the position shown in the several figures of the drawings, except when the foot'lever M is depressed. Above the small pulley 7c is arranged a large frictionpulley, mounted on a shaft, k", journaled in arms 70 projecting from a rock-shaft, 70, mounted in the frame D. This rock-shaft is provided with an arm, N, connected by a rod, a, to the foot-lever N, a spring, at, being arranged to thrust the rod upward when the lever N is not depressed, and thus hold the pulley It normally out of engagement with the pulley k. Differential pulley Z and a band, L, operate the shaft in the same manner that the shaft K is operated.

Upon the rock-shaft K and 7c are secured arms K provided with setscrews k which come into contact with the frame B, or a crossrod thereof, as shown, and serve to adjustably limit the upward throw of the arms M and N and their connected parts.

A cleaning-wheel, O, of felt, cloth, or other suitable soft material, is attached to the end of the shaft L in the manner shown, for the purpose hereinafter described.

The operation of my device is as follows: The parts being in the position shown, a circular box-bottom is placed within the centerer F and against-the disk d, the centerer being of an internal diameter equal to the diameter of the box-bottom. By means of the lever H the spindle E is moved. longitudinally to bring the clamping-disk e against the disk (1, when by its pressure the box-bottom will be forced upon the points (1 on the disk dto prevent its becoming uncentered in the subsequent operations. Thelever H is then moved back to its former position, thereby withdrawing the disk 6, the box-bottom being held in position within the centerer by means of the finger of the operator during this operation. The boxbody, which consists of a plain cylindrical tube, is then placed upon the box-holder G, which is of a proper size to receive it, the flange g preventing the body from passing too far over the box-holder. By means of the lever I the box-holder G, carrying the boxbody, is then moved up toward the spindle D, the projecting end of the box-body entering the centerer F and bearing against the box-bottom, whichisalreadyinplace. Theclanipingdisk 6 is then moved up by means of the lever H against the disk (Z, and the centerer F is slid back upon the spindle D out of the way. The box body and bottom are now clamped in the same relative position which they will occupy in the completed box, and are therefore ready to receive the paper covering which This paper covering consists of a strip of paper, or,

if desired, of two strips overlapping each other, the whole being of a width somewhat in excess of the length of the box, and being supplied with paste upon one side. This covering-paper may be supplied to the machine in strips of a suiiicient length; or itmay be drawn from a machine provided with a roll of paper and supplied with paste by passing over a suitable paste-roller. The end of this strip is laid over the boxbody, which is rotated either by hand or by depressing the foot-lever M, so as to bring the small friction-pulley K in contact with the large friction-pulley K on the spindle D. This rotary motion of the box body winds the paper around it, the end of the paper being turned over the projecting edge of the box-bottom by the operator during this rotation. It will be observed that the boxbottom, which is shown at Pin Fig 12, is somewhat greater in diameter than the boxbody P, and therefore projects out beyond it, leaving a corner, 19, in which the paper covering 1) must be forced. This laying on of the paper covering may be effected to a certain extent byhand; but'for the finishingI employ the tool shown in Fig. 11 of the drawings. This consists of a suitable handle, Q, upon which is mounted a roller, Q, consisting of a disk provided with a projecting hub, g, which is undercut next to the disk, forming a groove, g.

an adjustable tool-rest, R, of any approved construction, to support the tool while in operation. The paper covering, having been applied over the whole outer surface of the box body and lapped over the end of the bottom, as hereinbefore described, by depressing the foot-lever N the large friction -pulley k is brought in contact with the small friction-pulley It on the spindle D, and a rapid rotary motion thereby imparted to the spindle, and consequently to the box, which is clamped against it. The roller-tool is then applied to the box at thejunction of the bottom and body, the disk portion thereof resting against the under side of the bottom and the hub portion against the body, while the groove q accommodates the projecting periphery at the bottom. brings all parts of thejoint between the body and the bottom under the action of the rollertool, which presses the paper covering properly into place. The connection between the body and the bottom being now complete, the box-holder G is removed by throwing back the lever I, and. the projecting end of the paper covering may be then turned down into the interior of the box by the operator, the box body being-supported during this operation by its connection with the bottom, which is clamped between the two disks. The lever H is then swungback and the complete box removed, when the machine is in position to again perform the series of operations above described. Any paste that accumulates upon The rotary motion imparted to the box the roller-tool may be readily removed by holding the same against the continually-rotating cleaning-wheel O.

' The clamping-disks, centerer, and boxholder are all detachable, so that they may be,

removed and others substituted when it is desired to adapt the machine to the construction of a different-sized box, and sets of these parts may be constructed to fit any sized box which it is desired to make. In case the boxbody be longer or shorter,tl1e frame 0 may be moved farther away from or nearer to the frame B, according to the length of body desired. The relative position which the movable clamping'disk and box-former occupy at the extreme limits of their motion, both-with respect to each other and with respect to the fixed clamping-disk, may be varied at will by adjusting the fulcra of the levers H and I, as hereinbefore described. Thespring i, interposed between the sleeve 1 and the collar on the rod 1, will, in case the box-body on the box-holder is of a greater length than that for which the machine is set, yield to the advance of the lever, when the box-holder and rod 1 can no longer advance, and allow the lever to pass over the locking-cone without crushing the box-body.

It is obvious that various mechanical modifications may be made in the construction shown and described without departing from the principle of my invention. For instance, both frames may be made adjustable or both may be fixed, or the frame 13 made adjustable and the frame 0 fixed. Although I have shown a preferred form of mechanism for imparting either a slow or a rapid motion to the spindle D, it is obvious that other mechanism may be employed to rotate the said spindle, if desired. The machine may readily be adapted to the construction of square or polygonal boxes by constructing the clampingdisks, centerer, and box-holder of the proper shape. Although the machine is especially well adapted for the construction of boxes of the description shown in Fig. 12 of the drawings, having a bottom projecting out beyond the body of the box, still it is evident that the machine is also adapted to the construction of boxes in which the bottom is of adiameter equal to the external diameter of the body, or in which the bottom is equal to the internal diameter of the body, and is placed within the same. Itherefore do not wish to be understood as limiting myself strictly to the precise construction hereinbefore described, and shown in the drawings.
